Na[B(hfip)4] (hfip = OC(H)(CF3)2): A weakly coordinating anion salt and its first application to prepare ionic liquids

The fast, high yield synthesis and full characterization of Na[B(hfip) 4] (hfip: OC(H)(CF3)2) from NaBH4 and hexafluoroisopropanol (hfipH) is presented. By anion metathesis, five [B(hfip)4]- salts with classical/functionalized ionic liquid (IL) cations with melting points between 0 ([C6MIM] +[B(hfip)4]-) and 113 °C ([C 4MMorph]+[B(hfip)4]-) were prepared. Four of these qualify as ILs and one as room temperature IL (RTIL). The properties of the borate anion [B(hfip)4]- and its aluminum analogue [Al(hfip)4]- were compared based on the available structural information from XRD. Viscosities (10.3 (90 °C) to 855 (0 °C) mPa s-1) and conductivities (0.603 (30 °C) to 4.844 (90 °C) mS cm-1) were measured between 0 and 90 °C, and described by the Vogel-Fulcher-Tammann (VFT) equations. The properties of the [B(hfip)4]- ILs were analyzed in the context of the anion-dependent molecular volume Vm-viscosity-/conductivity- correlations, also in comparison to ILs with [BF4] -/[PF6]-, [N(CN)2]-, [Tf2N]- and [Al(hfip)4]- counterions. The viscosities and conductivities of [B(hfip)4] - ILs are slightly inferior to [Al(hfip)4]- ILs, similar to/better than all other anions given above. According to the Walden plots, the ionicity of the [B(hfip)4]- ILs may at least be classified as "good". By sharp contrast to the [Al(hfip) 4]- ILs, the [B(hfip)4]- ILs have good stability against humidity/water. Thus, handling of [B(hfip) 4]- ILs in an open laboratory atmosphere over hours and days is allowed and further facilitates the use of this new IL class. The Royal Society of Chemistry 2011.
